From structural assembly to MRO, 3MTM engineers products that address the full aircraft lifecycle. Coast-Line stocks the materials your program needs, ready to ship.
Structural Assembly
3MTM structural adhesives and film adhesives are proven across metallic and composite airframe structures. Whether you’re bonding aluminum skins, co-curing composite stiffeners, or closing out honeycomb panels, 3MTM delivers the bond strength and process reliability aerospace programs demand.
Advanced Ceramics
When heat is the enemy, Nextel delivers. 3M™ Nextel™ Ceramic Fibers and Textiles are continuous-filament ceramic oxide materials engineered to meet the most demanding thermal, mechanical, and electrical requirements in aerospace — including FAA criteria for aircraft firewalls and NASA standards for spacecraft heat shielding. Lightweight and flexible, yet capable of withstanding continuous temperatures up to 2,372°F (1,300°C), Nextel is the material of choice when conventional alternatives simply won’t survive.

MRO & Maintenance
Two-part epoxy and acrylic adhesives that cure at room temperature or with mild heat. Engineered for high-strength bonding of metals and composites in aerospace assembly and repair applications.
Supported and unsupported film adhesives for co-curing and secondary bonding of composite and metal structures. Available in a range of areal weights and cure temperatures to match your process.
Fuel-resistant, flexible polysulfide sealants for fuel tank faying surfaces, fillet sealing, and pressure sealing applications. Available in multiple cure rates and packaging configurations.
Discs, belts, and sheets engineered for composite and metal surface preparation, paint stripping, and finishing operations. Consistent cut rates and long life reduce downtime in production and MRO environments.
A broad range of masking, splicing, surface protection, and high-temperature process tapes designed for aerospace manufacturing environments. Includes polyimide, PTFE, and aluminum foil constructions.
Surface pre-treatment solutions that improve adhesive bond performance on metals, composites, and plastics. Includes the widely specified AP86A adhesion promoter and corrosion-inhibiting bond primers for aluminum and titanium.
